1. Underhood Fuse Box:
* Location: Open the hood and look for a large, black plastic box usually located near the battery. It might have a cover labeled "Power Distribution Box" or something similar.
* Access: The cover is usually held on by clips or screws. Carefully remove the cover to access the fuses.
* Fuse Identification: There's usually a diagram on the inside of the cover showing the fuse layout and what each fuse protects. If you can't find the diagram, consult your owner's manual.
* Fuse Replacement: Carefully pull out the blown fuse using fuse puller tool (often found in the box) or needle-nose pliers. Never use metal tools that could cause a short. Compare the blown fuse to the diagram to determine its amperage rating. Replace it with a fuse of the *exact same amperage*. Using a higher amperage fuse is dangerous and could cause a fire.
2. Interior Fuse Panel:
* Location: This is typically located under the dashboard, usually on the driver's side. You might need to remove a panel or cover to access it. The exact location and access method will vary slightly depending on trim level. The best way to find it is to consult your owner's manual; it will show you a picture and specific instructions. It might be under the steering wheel column or tucked away slightly higher.
* Access: The panel usually has a release mechanism (clips or screws) which is detailed in your owner's manual. Again, carefully remove the panel without damaging it.
* Fuse Identification and Replacement: Follow the same procedure as for the underhood fuse box: use the diagram (found on the inside of the panel or in your owner's manual) to identify the blown fuse and replace it with one of the *same amperage*.
Important Notes:
* Owner's Manual: Your owner's manual is your best friend for this task. It will have detailed diagrams and instructions specific to your 2003 Ford Expedition Eddie Bauer.
* Safety: Always disconnect the negative terminal of your battery before working on electrical components if you're not comfortable. This is a safety precaution to prevent electrical shocks.
* If the fuse blows again immediately: This usually indicates a more serious underlying electrical problem. Do not keep replacing the fuse. Take your vehicle to a qualified mechanic to diagnose and repair the root cause.
If you're unsure about any step, it's best to consult your owner's manual or take your vehicle to a professional. Working with car electrical systems can be dangerous if you're not familiar with them.
